Ivy Porter and Shane McLaughlin have relied solely on one another since their troubled childhoods, but their unwavering devotion will soon be tested… Orphaned and forsaken, Ivy and Shane band together at the tender ages of eight and ten in order to survive the brutal streets of nineteenth-century Chicago. Years later, displaced by the historic fire that razes the city, the loyal duo migrates to Colorado. The next decade is spent gambling, picking pockets, and scamming rich silver barons, but their hubris pits them against one very determined small-town marshal intent on bringing them to justice. Throughout, Ivy believes it’s only a matter of time before Shane regards her as someone more than his childhood confidante or partner in crime, but any greater intimacies between them are quelled by Shane’s traumatic past. Feeling increasingly dissatisfied with the life they’ve cobbled together, Ivy posits an ultimatum, but Shane reacts by revealing a betrayal so deep as to tear them apart. Benchmarked by two of the greatest natural calamities to take place in nineteenth-century America—the Great Chicago Fire of 1871 and the catastrophic winter of 1886-87—a final act of faith high in the Rocky Mountains seals the interwoven fates of two childhood friends, a marvelous surprise christened Jack, and the unexpectedly sympathetic lawman who brings them all together again.
